因为最近工作用NGUI比较多，修改图集时还没原图，有时候需要把图集重新切割开来，用代码会比较方便，一下贴出主要代码首先读取NGUI图集的信息[csharp] view plaincopyUIAtlas mAtlas  ;           GameObject[] SelectedAsset=Selection.gameObjects;           if (SelectedAsset.Length == 1)           {               mAtlas = SelectedAsset[0].GetComponent
     
      ();                   if (mAtlas != null)               {                   string atlasFile = string.Format("{0}.txt", mAtlas.name);                   string atlasPng = string.Format("{0}.png", mAtlas.name);                   char[] ch = { '.' };                   string path = AssetDatabase.GetAssetPath(SelectedAsset[0]);                   FileInfo aFileinfo = new FileInfo(path);                   string th = aFileinfo.DirectoryName;                   string[] strs = path.Split(ch);                     if (File.Exists(atlasFile))                   {                       File.Delete(atlasFile);                   }                   StreamWriter sw = new StreamWriter(strs[0] + ".txt");                   StringBuilder sb = new StringBuilder();                   foreach (UIAtlas.Sprite sprite in mAtlas.spriteList)                   {                       sb.AppendLine(string.Format("name:{0}, coordinate:{1}", sprite.name, sprite.outer));                   }                     sw.Write(sb.ToString());                   sw.Close();                     string[] arg = new string[2];                   arg[0] = atlasPng;                   arg[1] = th;                   //print(arg[0]);                   //print(arg[1]);                   string path_2 = AssetDatabase.GetAssetPath(Resources.Load("CutAltas/output"));                   FileInfo aFileinfo_2 = new FileInfo(path_2);                   string th_2 = aFileinfo_2.DirectoryName;                   print(th_2);                   string s = th_2 + "\\Start.exe";  这是主要的代码，接下来用vs编写一个程序切割图集，主要代码如下[csharp] view plaincopynamespace WindowsFormsApplication1  {      public partial class Form1 : Form      {          string[] p;          string path = string.Empty;          public Form1(string[] s)          {              InitializeComponent();              p = s;              ImageName.Text = p[0];              path = p[1];          }            private void button1_Click(object sender, EventArgs e)          {              CutImage(path);              Application.Exit();                       }                    void CutImage(string p)           {              string path=@"c:\Documents and Settings\Administrator\桌面\";              string savePath=string.Empty;              string imagePath = p + "\\"+ImageName.Text;              string textPath = string.Empty;              Image img = Image.FromFile(imagePath);                            char[] c = { '.' };              string st= ImageName.Text;              string[] sts = st.Split(c);              savePath = path + sts[0];              if (!Directory.Exists(savePath))              {                  Directory.CreateDirectory(savePath);              }              textPath = p + "\\"+sts[0]+".txt";              StreamReader sr = new StreamReader(textPath);                while (!sr.EndOfStream)              {                  string newLine = sr.ReadLine();               //   Regex reg = new Regex(@"name:(?P
      
       .+), coordinate:\(x:(?P
       
        \d+)\.00, y:(?P
        
         \d+)\.00, width:(?P
         
          \d+)\.00, height:(?P
          
           \d+)\.00\)"); // Regex regName = new Regex(@"\bname:\.*"); string patternName = @"\bname:\w*"; string patternX = @"\bcoordinate:\(x:\w*\.\d\d"; string patternY = @"\by:\d*\.\d\d"; string patternWidth = @"\bwidth:\d*\.\d\d"; string patternHeight = @"\bheight:\d*\.\d\d"; string name = savePath+"\\"; float x=0,y=0,width=0,height=0; char[] maoHao = { ':' }; MatchCollection imageName = Regex.Matches(newLine, patternName, RegexOptions.ExplicitCapture); foreach (Match nextMatch in imageName) { int index = nextMatch.Index; string result = nextMatch.ToString(); string[] re = result.Split(maoHao); name += re[re.Length - 1]; name += ".png"; // MessageBox.Show(re[1]); } MatchCollection positionX = Regex.Matches(newLine, patternX, RegexOptions.ExplicitCapture); foreach (Match nextMatch in positionX) { int index = nextMatch.Index; string result = nextMatch.ToString(); string[] re = result.Split(maoHao); x = float.Parse(re[re.Length - 1]); // MessageBox.Show(x.ToString()); } MatchCollection positionY = Regex.Matches(newLine, patternY, RegexOptions.ExplicitCapture); foreach (Match nextMatch in positionY) { int index = nextMatch.Index; string result = nextMatch.ToString(); string[] re = result.Split(maoHao); y = float.Parse(re[re.Length-1]); // MessageBox.Show(y.ToString()); } MatchCollection widths = Regex.Matches(newLine, patternWidth, RegexOptions.ExplicitCapture); foreach (Match nextMatch in widths) { int index = nextMatch.Index; string result = nextMatch.ToString(); string[] re = result.Split(maoHao); width = float.Parse(re[re.Length - 1]); // MessageBox.Show(width.ToString()); } MatchCollection heights = Regex.Matches(newLine, patternHeight, RegexOptions.ExplicitCapture); foreach (Match nextMatch in heights) { int index = nextMatch.Index; string result = nextMatch.ToString(); string[] re = result.Split(maoHao); height = float.Parse(re[re.Length - 1]); // MessageBox.Show(height.ToString()); // MessageBox.Show("Name: " + name + "x :" + x.ToString() + "y :" + y.ToString() + "width :" + width.ToString() + "height :" + height.ToString()); } // MessageBox.Show("Name: "+name+"x :"+x.ToString()+"y :"+y.ToString()+"width :"+width.ToString()+"height :"+height.ToString()); Bitmap bmp = new Bitmap(img); Rectangle rec = new Rectangle((int)x, (int)y, (int)width, (int)height); bmp = bmp.Clone(rec, bmp.PixelFormat); bmp.Save(name, System.Drawing.Imaging.ImageFormat.Png); } MessageBox.Show("切割完成，返回桌面查看！"); // Bitmap bmp = new Bitmap(img, 100, 100); // bmp.Save(path + "newImage.jpg"); } } } 最后unity要调用vs生成的程序，并且传进参数static bool StartProcess(string filename, string[] args) { //print("wwww"); try { string s=""; foreach(string arg in args) { s += string.Format("\"{0}\" ", arg); } s = s.Trim(); print(s); Process myprocess = new Process(); ProcessStartInfo startInfo = new ProcessStartInfo(filename,s); myprocess.StartInfo = startInfo; myprocess.StartInfo.UseShellExecute = false; myprocess.Start(); return true; } catch (Exception ex) { UnityEngine.Debug.Log("出错原因：" + ex.Message); } return false; }
